Give reason for the following observation The smell of hot sizzling food reaches you several metres away but to get the smell from cold food you have to go close.​

The smell of hot sizzling food reaches you several metres away, but to get the smell from cold food you have to go close because the kinetic energy of the particles of matter increases with the increase in temperature. In cold foods, kinetic energy is less while in hot foods, kinetic energy is more

hope this helps

Smell spreads due to diffusion. In hot food the molecules have a lot of kinetic energy , and they therefore spread fast , whereas in cold food the kinetic energy of the molecules are less and they don't spread far.

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.
